Liberon Spirit Sanding Sealer effectively readies bare wood and MDF surfaces for finishing with wax on decorative items. This sealer reduces the amount of wax needed and contains lubricants that facilitate sanding. For durable finishes on tabletops, shelves, and other surfaces, opt for Liberon Finishing Oil instead. When used on floors, first apply Liberon Floor Sealer, followed by Floor Wax for optimal results.
